    li09c_3970351

      Hi Expert,

        We use your PSOC4 Capsense make a product for liquid level check, we found the the test is not good when the plastic box wall is bigger than 2mm thick. There are only 0.5% rate of  ADC value changed. But for little thickness(<0.5mm), there are 10% change rate of ADC value .

          We have below questions?

      1. What is the max thickness of plastic box wall for this Capsense liquid level test.

      2. Can we get a design to satisfy this bigger thickness liquid level test with tuning the Capsense sensor pad bigger or other trick?
